UNISONIC TECHNOLOGIES CO., LTD 88NXX Preliminary CMOS IC BUILT-IN DELAY CIRCUIT HIGH-PRECISION VOLTAGE DETECTOR DESCRIPTION The UTC 88NXX is a high-precision voltage detector developed basing on CMOS technology. The detection voltage is fixed internally. A time delayed reset can be accomplished with an external capacitor. N-ch open-drain output form is available. The UTC 88NXX is generally used for power supply monitor of portable equipment such as notebook PCs, digital still cameras, PDAs, and mobile phones, constant voltage power monitor of cameras, video equipment and communication equipment, and power monitor or reset of CPUs and microcomputers. FEATURES * Extremely Low Current Dissipation : 1.2μA Typ. (Detection Voltage ≥ 1.5 V @ VDD=3.5 V) * ±2.0 % Accuracy Detection Voltage * Hysteresis Characteristics: 5% TYP * Detection Voltage varies from 1.5V to 6.0V with 0.1V step * Output Forms: N-ch open-drain output (when it is in Active-Low) ORDERING INFORMATION Ordering Number Lead Free Halogen Free 88NXXL-AF5-R 88NXXG-AF5-R 88NXXL-AD4-R 88NXXG-AD4-R Note: XX: Output Voltage, refer to Marking Information.
